I always enjoy reading his posts and he has helped me in the past. The forums there did seem to be getting a bit stale for a while so haven't been there much lately. The whole site seems the owner has lost interest or...busy doing something else. Thanks for explaining some of the difference in the motherboards. I was under the false impression the boards were clones of the Apple boards. I didn't realize they had so many differences. I do understand the architecture issues and differences at least as much as I need to.Thanks to you. Will S
